1 Pavement Design Support IAC Corridor Analysis Studies Identification of Project Limits Cause of Pavement Problem Optimal Repair Strategy 10 year Rehabilitation Plan Priority and Cost Joint Effort with Districts and Construction Division PD Magdy Mikhail

2 Nominated Projects FY 2011 Odessa IH 10 and 20 Lubbock US 60, US 62 and US 84 Bryan IH 45 and US 290 Corpus Christi US 77 and US 281 Austin US 183 and SH 21

3 Steps in Typical Corridor Analysis Conduct a full GPR survey of all lanes of highway Meet with District office personnel to; Assemble typical sections and type and date of last treatment Define section breaks Summarize PMIS data for projects Provide traffic estimates for each section Meet with Area Engineers and their staff to; Discuss section histories Identify their priorities and treatment preferences Plan and Execute an FWD and DCP test program Plan and Execute a field sampling program including coring to validate defects and auguring (if needed) Conduct laboratory testing where required (FDR, Overlay tests, etc)

4 GPR Runs Confirming section breaks - identifying subsurface deflects core locations

5 Steps in Typical Corridor Analysis Conduct a full GPR survey of all lanes of highway Meet with District office personnel to; Assemble typical sections and type and date of last treatment Define section breaks Summarize PMIS data for projects Provide traffic estimates for each section Meet with Area Engineers and their staff to; Discuss section histories Identify their priorities and treatment preferences Plan and Execute an FWD and DCP test program Plan and Execute a field sampling program including coring to validate defects and auguring (if needed) Conduct laboratory testing where required (FDR, Overlay tests, etc)

6 Field Sampling

7 Steps in Typical Corridor Analysis Conduct a full GPR survey of all lanes of highway Meet with District office personnel to; Assemble typical sections and type and date of last treatment Define section breaks Summarize PMIS data for projects Provide traffic estimates for each section Meet with Area Engineers and their staff to; Discuss section histories Identify their priorities and treatment preferences Plan and Execute an FWD and DCP test program Plan and Execute a field sampling program including coring to validate defects and auguring (if needed) Conduct laboratory testing where required (FDR, Overlay tests, etc)

8 Steps in Typical Corridor Analysis, cont d) Analyze all of the data collected Prepare a 10 year plan for each project identified in the corridor including; Project limits, current condition and cause of pavement problems Prioritize projects in terms of when treatment is required, as follows 0 2 years (top priority) needs action now 2 5 years distresses occurring will fail in near future 5 10 years section good for now but problems expected > 10 year section is structurally sound needs an effective maintenance/resurfacing program only Recommend best rehabilitation option and estimated cost for each project Summarize all information for each section into single page action plan sheet

9 Steps in Typical Corridor Analysis, cont d) Presentation of results to District personnel Provide copies of all data collected to District personnel Provide training on how to use the Pavecheck and Paveview systems for plan development
